Hennessey is once again bringing its super station wagon out to the drag strip. The Texas tuner has taken Cadillac's 556-horsepower fast family-hauler and tweaked it so that the 6.2-liter V8 now produces 650 hp. We previously showed you how it fared against an (outdated) Porsche 911 Turbo, and now Hennessey has brought the CTS-V Sport Wagon back to the track, and this time, the opponent in the other line is driving a Nissan GT-R.

A 2011 Nissan GT-R to be more precise. The model that produces 485 horsepower and runs down Hennessey's track in 11.8-seconds. That's a hair slower than the 11.7-second run ripped off by the Sport Wagon - an amazing time for the 4,398-pound American muscle machine.

However, the 2012 Nissan GT-R pumps out 530 horsepower, runs from 0-60 miles per hour in less than three seconds and will cover a quarter-mile in about 11.6 seconds. Now, you can take that to mean Hennessey should've run against the newer GT-R... or that they've built one hell of a station wagon. Click past the jump to watch the two cars run down the strip.
